Technical Field

[0001] This utility model relates to the field of calendering technology, specifically a two-roll calendering machine for textile finishing. Background Technology

[0002] Textiles refer to products that have undergone textile processing or have already been processed, including yarns, woven fabrics, knitted fabrics, braided fabrics, etc. In order to make textiles uniform, stable in size and shape, improve the hand feel of textiles, enhance the durability of textiles, and endow textiles with special properties, it is necessary to use a two-roll calender to finish textiles.

[0003] A Chinese patent application with publication number CN 115491842 A discloses a two-roll calender for finishing chemical fiber silk fabrics, belonging to the technical field of fabric finishing equipment. It includes a housing, within which are installed a fabric spreading and humidifying device, a preheating box, a calendering mechanism, a cooling and shrinking mechanism, and a material receiving mechanism. Fabric feeding plates are welded between the two side walls of the housing, and silk fabric is laid between the feeding plates. The fabric spreading and humidifying device includes a first roller, a second roller, and a humidifying nozzle. Both the first and second rollers are fixedly installed on the feeding plates. The preheating box includes a fabric blocking rod, a heating plate, and a box body. The fabric blocking rod is rotatably connected to the inner wall of the box body, and the heating plate is fixedly installed between the inner walls of the box body. This invention can automatically spread the processed fabric, avoiding wrinkles, reducing heat loss from the calendering mechanism, thus reducing energy consumption and making the equipment more energy-efficient. It can also automatically clean the calendering mechanism, improving product quality, and can better collect the processed fabric, further enhancing product quality.

[0004] Existing calenders have difficulty in automatically detecting and adjusting the tension of textiles during the calendering process. When the textiles are relaxed, wrinkles are easily formed on the calendered textiles, resulting in poor tension adjustment and affecting the calendering quality of the textiles. Therefore, a two-roll calender for textile finishing is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems existing in the existing technology, this utility model proposes a two-roll calender for textile finishing.

[0006] The technical solution adopted by this utility model to solve its technical problem is a two-roll calender for textile finishing, including a base. Two guide plates are symmetrically installed on the base. Guide grooves are formed on the guide plates. A stepper motor is mounted on one of the guide plates via a machine base. A first lead screw is mounted on the output shaft of the stepper motor. The first lead screw is rotatably mounted on the inner wall of the guide groove. A guide block is assembled in the guide groove. A lifting block is mounted on the guide block. The lifting block has a moving groove. A moving block is assembled in the moving groove. A tension roller is rotatably mounted on the moving block. A first electrode plate is mounted on the bottom side of the movable block, and a second electrode plate is mounted on the inner wall of the movable groove. An indicator light is mounted on the lifting block, and the indicator light is connected to the first and second electrode plates via an internal circuit. A fixed frame is mounted on the base via a fixed seat. Two sets of rollers are rotatably mounted on the fixed frame, and gears are fixedly mounted on the output shafts of the two sets of rollers. The two gears mesh with each other. A drive motor is mounted on the side wall of the fixed frame via a machine base. The output shaft of the drive motor is fixedly connected to the output shaft of one of the rollers. A control panel is mounted on the fixed frame. The control panel is connected to indicator lights and a stepper motor via internal circuitry. A release assembly is mounted on the base. The release assembly includes a first support frame, on which a first motor is mounted via a base. A release roller is mounted on the output shaft of the first motor and is rotatably mounted on the first support frame. Textile is wound on the release roller. A take-up assembly is mounted on the base. The take-up assembly includes a second support frame, on which a second motor is mounted via a base. A take-up roller is mounted on the output shaft of the second motor and is rotatably mounted on the second support frame. The base is equipped with multiple sets of fixing plates, on which guide rollers are rotatably mounted. These guide rollers contact the textile and, under their own weight, continuously press the textile downwards, keeping it taut. When the textile is taut, it blocks the tension rollers, preventing them from moving further downwards. This allows for the adjustment of the textile's tension. This structure can autonomously detect and adjust the textile's tension, preventing wrinkles from appearing on the calendered textile. It improves the adjustability of the textile's tension and enhances the calendering quality.

[0007] Preferably, one set of fixed plates is equipped with a limiting component, which includes a mounting plate with a groove. A second lead screw is rotatably mounted on the inner wall of the groove. A damping wheel is mounted on one end of the second lead screw, and the damping wheel is in contact with the fixed plate. The threads on the second lead screw are symmetrically opposite in direction. Two sets of sliders are symmetrically assembled in the groove. A limiting plate is mounted on the slider, and two limiting wheels are rotatably mounted on the limiting plate. The two sliders drive the two limiting plates to move synchronously relative to each other, so that the two limiting plates are in contact with the edge of the textile, and the textile is placed between the two limiting wheels. The two limiting plates and the two limiting wheels work together to accurately limit the textile, which helps to improve the neatness of the textile winding.

[0008] The advantages of this utility model are:

[0009] 1. This utility model uses a tension roller that contacts the textile and presses it downwards under its own weight, thus putting the textile in a tensioned state. When the textile is in a tensioned state, it will block the tension roller, preventing it from moving further downwards. This achieves the adjustment of the textile's tension. This structure can autonomously detect and adjust the textile's tension, avoiding wrinkles on the calendered textile, improving the adjustability of the textile's tension, and ultimately improving the calendering quality of the textile.

[0010] 2. This utility model uses two sliders to drive two limiting plates to move synchronously relative to each other, so that the two limiting plates are in contact with the edge of the textile and the textile is placed between the two limiting wheels. The two limiting plates and the two limiting wheels work together to accurately limit the textile, which helps to improve the neatness of the textile winding. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0019] Please see Figure 1-4As shown, a two-roll calender for textile finishing includes a base 1. Two guide plates 2 are symmetrically mounted on the base 1. Guide grooves 3 are formed on the guide plates 2. A stepper motor 4 is mounted on one of the guide plates 2 via a machine base. A first lead screw 5 is mounted on the output shaft of the stepper motor 4. The first lead screw 5 is rotatably mounted on the inner wall of the guide groove 3. A guide block 6 is assembled inside the guide groove 3. A lifting block 7 is mounted on the guide block 6. The lifting block 7 has a moving groove 8. A moving block 9 is assembled inside the moving groove 8. A tension roller 10 is rotatably mounted on the moving block 9. A first electrode plate 11 is mounted on the bottom side of the moving block 9. A second electrode plate 12 is mounted on the inner wall of the moving groove 8. An indicator light 13 is mounted on the lifting block 7. The indicator light 13 is connected to the first electrode plate 11 via an internal circuit. 1. The base 1 is connected to the second electrode plate 12. A fixed frame 14 is mounted on the base 1 via a fixed seat. Two sets of rollers 15 are rotatably mounted on the fixed frame 14. Gears 16 are fixedly mounted on the output shafts of the two sets of rollers 15, and the two gears 16 mesh with each other. A drive motor 17 is mounted on the side wall of the fixed frame 14 via a machine base. The output shaft of the drive motor 17 is fixedly connected to the output shaft of one of the rollers 15. A control panel 32 is mounted on the fixed frame 14. The control panel 32 is connected to the indicator light 13 and the stepper motor 4 via an internal circuit. A release assembly is mounted on the base 1. The release assembly includes a first support frame 18. A first motor 19 is mounted on the first support frame 18 via a machine base. A release roller 20 is mounted on the output shaft of the first motor 19. The textile 21 is wound on the release roller 20 and rotatably mounted on the first support frame 18. A take-up assembly is mounted on the base 1, including a second support frame. A second motor is mounted on the second support frame via a base, and a take-up roller 22 is mounted on the output shaft of the second motor. The take-up roller 22 is rotatably mounted on the second support frame. Multiple sets of fixing plates 23 are mounted on the base 1, and guide rollers 24 are rotatably mounted on the fixing plates 23. During operation, existing calenders have difficulty autonomously detecting and adjusting the tension of the textile 21 during calendering. When the textile 21 is relaxed, wrinkles easily appear on the calendered textile 21, resulting in poor tension adjustability and affecting the calendering quality of the textile 21. The first electric... The machine 19 operates, driving the release roller 20 to rotate. The release roller 20 releases the textile 21, which then passes through several guide rollers 24 and tension rollers 10 in sequence, and enters between two rollers 15. The drive motor 17 operates, driving one of the rollers 15 to rotate. The roller 15 drives the gear 16 on it to rotate, and the gear 16 drives the other gear 16 to rotate. The two gears 16 rotate synchronously relative to each other, and the two gears 16 drive the two rollers 15 to rotate synchronously relative to each other. The textile 21 is clamped by the rollers 15. Through the rolling action, the fibers in the textile 21 are deformed in a short time, increasing the contact area between fibers and enhancing the surface gloss of the textile 21, thus realizing the calendering process of the textile.

[0020] After the textile 21 passes around several guide rollers 24, the second motor drives the take-up roller 22 to rotate, and the take-up roller 22 takes up the textile 21.

[0021] During this process, the tension detection component detects the tension of the textile 21. When the textile 21 is in a tensioned state, it will push the tension roller 10 upward, applying a supporting force to the tension roller 10, causing the moving block 9 to be suspended in the moving groove 8. When the textile 21 becomes slack, the supporting force of the textile 21 on the tension roller 10 disappears. At this time, the tension roller 10 will move vertically downward under its own weight, driving the moving block 9 on it to move vertically downward. The moving block 9 drives the first electrode plate 11 on it to move vertically downward, so that the first electrode plate 11 contacts the second electrode plate 12. At this time, the internal circuit of the indicator light 13 is turned on, and the indicator light 13 sends an electrical signal to the control panel 32. After receiving the electrical signal, the control panel 32 controls the stepper motor 4 to operate, driving the first lead screw 5 to rotate. The first lead screw 5 drives the guide block 6 on it to move vertically downward. The guide block 6 drives the lifting block 7 to move vertically downward. The lifting block 7 drives the moving block 9 on it to move vertically downward. The moving block 9 drives the first lead screw 5 to move vertically downward. The tension roller 10 moves vertically downwards until it contacts the textile 21. Under its own weight, it continuously presses the textile 21 downwards, putting it into a tensioned state. When the textile 21 is tensioned, it blocks the tension roller 10, preventing it from moving further downwards. However, the lifting block 7 continues to move downwards, causing the first electrode plate 11 and the second electrode plate 12 to separate quickly. The internal circuit of the indicator light 13 is disconnected, and the electrical signal of the indicator light 13 disappears. At this time, the control panel 32 controls the stepper motor 4 to stop operating, causing the lifting block 7 to stop moving downwards. This achieves the adjustment of the tension of the textile 21. When the textile 21 becomes slack again, the above steps are repeated, and the tension roller 10 adjusts the tension of the textile 21 again. This structure can autonomously detect and adjust the tension of the textile 21, avoiding wrinkles on the calendered textile. This improves the adjustability of the tension of the textile 21 and enhances the calendering quality of the textile 21.

[0022] Please see Figure 5As shown, a limiting component is installed on one of the fixed plates 23. The limiting component includes a mounting plate 25, on which a groove 26 is provided. A second lead screw 27 is rotatably mounted on the inner wall of the groove 26. A damping wheel 28 is installed at one end of the second lead screw 27. The damping wheel 28 is in contact with the fixed plate 23. The thread directions on the second lead screw 27 are symmetrical and opposite. Two sets of sliders 29 are symmetrically assembled in the groove 26. A limiting plate 30 is installed on the slider 29. Two limiting wheels 31 are rotatably mounted on the limiting plate 30. During operation, the existing calender has difficulty accurately limiting the textile 21 during the calendering process, resulting in poor neatness of the textile 21 winding. By rotating the damping wheel 28, the second lead screw 27 is driven to rotate. The second lead screw 27 drives the two sliders 29 on it to move synchronously relative to each other. The two sliders 29 drive the two limiting plates 30 to move synchronously relative to each other, so that the two limiting plates 30 are in contact with the edge of the textile 21, and the textile 21 is placed between the two limiting wheels 31.

[0023] The textile 21 is clamped and calendered by the rollers 15, and then the textile 21 passes around several guide rollers 24. During this process, two limit plates 30 and two limit wheels 31 work together to accurately limit the textile 21. Then, the second motor drives the take-up roller 22 to rotate, and the take-up roller 22 takes up the textile 21, which helps to improve the neatness of the textile 21 being taken up.

[0024] Working principle: Existing calenders, during the calendering process of textile 21, struggle to autonomously detect and adjust the tension of the textile 21. When the textile 21 is relaxed, wrinkles easily appear on the calendered textile 21, resulting in poor tension adjustability and affecting the calendering quality. The first motor 19 operates, driving the release roller 20 to rotate. The release roller 20 releases the textile 21, which then passes through several guide rollers 24 and tension rollers 10 before entering between two rollers 15. The drive motor 17 operates, driving one roller 15 to rotate. This roller 15 drives a gear 16, which in turn drives the other gear 16. The two gears 16... The two gears 16 drive the two rollers 15 to rotate synchronously relative to each other. The textile 21 is clamped by the rollers 15. Through the rolling action, the fibers in the textile 21 are deformed in a short time, which increases the contact area between the fibers and enhances the surface gloss of the textile 21, thus realizing the calendering process of the textile. After the textile 21 passes through several guide rollers 24, the second motor drives the take-up roller 22 to rotate, and the take-up roller 22 takes up the textile 21. During this process, the tension detection component detects the tension of the textile 21. When the textile 21 is in a tensioned state, the textile 21 will push the tension roller 10 upward. The textile 21 applies a supporting force to the tension roller 10, so that the moving block 9 is suspended in the moving groove 8.When the textile 21 slackens, the upward support force of the textile 21 on the tension roller 10 disappears. At this time, the tension roller 10 will move vertically downward under its own weight, causing the moving block 9 on it to move vertically downward. The moving block 9 causes the first electrode plate 11 on it to move vertically downward, so that the first electrode plate 11 contacts the second electrode plate 12. At this time, the internal circuit of the indicator light 13 is turned on, and the indicator light 13 sends an electrical signal to the control panel 32. After receiving the electrical signal, the control panel 32 controls the stepper motor 4 to operate, driving the first lead screw 5 to rotate. The first lead screw 5 drives the guide block 6 on it to move vertically downward, and the guide block 6 drives the lifting block 7 to move vertically downward. As the lifting block 7 moves downwards, the lifting block 7 drives the moving block 9 on it to move vertically downwards. The moving block 9 then drives the tension roller 10 on it to move vertically downwards until the tension roller 10 contacts the textile 21. Under its own weight, the tension roller 10 continuously presses down on the textile 21, putting it into a tensioned state. When the textile 21 is in a tensioned state, it will block the tension roller 10, preventing it from moving further downwards. However, the lifting block 7 will continue to move downwards, causing the first electrode plate 11 and the second electrode plate 12 to quickly separate. The internal circuit of the indicator light 13 is disconnected, and the electrical signal of the indicator light 13 disappears. At this time, the control panel 32 stops the stepper motor 4. The operation is stopped, causing the lifting block 7 to stop moving downwards, thus adjusting the tension of the textile 21. When the textile 21 becomes slack again, the above steps are repeated, and the tension roller 10 adjusts the tension of the textile 21 again. This structure can autonomously detect and adjust the tension of the textile 21, avoiding wrinkles on the calendered textile, improving the adjustability of the tension of the textile 21, and improving the calendering quality of the textile 21. Existing calenders have difficulty accurately limiting the position of the textile 21 during the calendering process, resulting in poor uniformity of the textile 21 winding. By rotating the damping wheel 28... The second lead screw 27 rotates, causing the two sliders 29 on it to move synchronously relative to each other. The two sliders 29 then move the two limiting plates 30 synchronously relative to each other, bringing the limiting plates 30 into contact with the edge of the textile 21, with the textile 21 positioned between the two limiting wheels 31. The textile 21 is then clamped and calendered by the rollers 15, and subsequently passes over several guide rollers 24. During this process, the two limiting plates 30 and the two limiting wheels 31 work together to accurately limit the movement of the textile 21. Afterward, the second motor drives the take-up roller 22 to rotate, which winds up the textile 21, improving the neatness of the winding process.
